Publication number: 20230131715Abstract: A method and a system for spatial static map construction are provided. In the method, a three-dimensional space is scanned by using a LiDAR sensor to generate a LiDAR frame including multiple points in the three-dimensional space in a time sequence. As for each point in the LiDAR frame, a corresponding point closest to the point is found from a static map built according to the three-dimensional space, and a distance from the corresponding point is calculated. The point is labelled as a dynamic point if the distance is greater than a threshold, and otherwise labelled as a static point. Each labelled dynamic point is compared with points in N LiDAR frames generated before the time sequence, and corrected as a static point if included in the N LiDAR frames. The dynamic points in the LiDAR frame are removed, and each static point is updated to the static map.Type: ApplicationFiled: October 18, 2022Publication date: April 27, 2023Applicant: Coretronic Intelligent Robotics CorporationInventors: Yen-Yi Chen, Pei-Chi Hsiao, Chih-Chien Chen, Huang-Cheng Chiang
